Details

For compatibility reasons, Ubuntu 12.04 LTS shipped OpenSSL with TLSv1.2

This update re-enables TLSv1.2 by default now that the majority of

For problematic environments, TLSv1.2 can be disabled again by setting the
OPENSSL_NO_CLIENT_TLS1_2 environment variable before library
initialization.
